Know Your Enemies Nun How To Sin Sister by Sadpanda
Smart nun studying its enemies before marching to battle, because if you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle. Prepare yourself Satan, because a storm is coming to hell, and it's wearing a nun outfit.
